Regional development agency Yorkshire Forward will use the cash to award grants of up to £100,000 to large companies with more than 50 employees.
Last month it announced a £2m fund for smaller firms. The grants aim to cover costs not covered by insurance.
A spokesman said the £5m investment was a "direct response to calls from businesses for financial assistance."
Chairman Terry Hodgkinson said: "The resilience of the region's businesses and the effectiveness of the disaster recovery plans have ensured that businesses in the region were back in business just days after June's torrential downpours.
"Yorkshire Forward is now working with them to identify their concerns and needs.
"We have responded rapidly and taken decisive action to help businesses to bring their manufacturing capabilities back up to full capacity by getting vital equipment back in working order."
Businesses in Sheffield and Rotherham suffered particularly badly after the floods.
The Meadowhall shopping centre in Sheffield was closed for a week, costing it millions of pounds in lost revenue.
Another of the city's major employers, engineering firm Sheffield Forgemasters, was submerged under 6ft of water.
